Chapter 33.4, Problem 4SB
Summary Introduction
To review:
The description of the two examples of the life phases of long-living plant species.
Introduction:
Some plants are short lived and some are long lived, i.e., some plants have a short life span and some have a long life span. There are two factors genetic composition of plants and environmental conditions that determine the life span of a plant.

Review the life cycles of the three major plant groups (bryophyte or non-vascular plants, seedless vascular plants, and seed plants). Be able to identify the gametophyte and sporophyte generations in each plant group.
Make one graph that shows patterns of changes in the following characteristics, as the different plant groups (bryophytes or non-vascular plants, seedless vascular plants, and seed plants) appeared or evolved on land through time.
1) size of the gametophyte generation
2) size of the sporophyte generation
3) biomass (amount of organic material) stored in the sporophyte
4) degree of dependence on water for fertilization
Make sure the y- and x- axes of the graph, labels and title are included and correctly applied.
List the signiicant events in the evolution of land plants.
Describe two ways that non-vascular plants rely on water in the environment for reproduction?

- Plants Are Adapted to Life on Land Plants developed from a group of green algae (members of Kingdom Protista) called the charophytes. Like these green algae, plants have a life cycle called the alternation of generations. Draw a diagram of the basic life cycle of a plant, showing the alternation of the sporophyte and gametophyte generations. Unlike green algae that live in water, plants live on land. Being surrounded by air means that they risk losing too much water through evaporation and dying from dehydration.
